GIS Geographic Information System is a system intends to capture, Store, manage, manipulate, analyze the data. GIS system integrate data and convert it into maps. And as we know visuals are more powerful than words so it makes our understanding of data fast.

What is GIS ?

GIS is a tool to acquire geographic data and produce Geographic information. And generally those information are stored in tabular form. GIS can be defined as a “computer information system that can input, store, manipulate, analyze, and display geographically referenced (spatial) data to support decision making processes”.

Simply GIS visualize your data as a map. And these visualization makes the study interesting with interactive maps. It saves the time and make the system decisiveness that is main requirement.

The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. The 48 contiguous states and Washington, D.C., are in North America between Canada and Mexico. Alaska is an exclave in the far northwestern part of North America, connected only to Canada, and Hawaii is an archipelago in the mid-Pacific. Territories of the United States are scattered throughout the Pacific Ocean and the Caribbean Sea.

According to the numerous decisions of the United States Supreme Court, the 50 individual states and the United States as a whole are each sovereign jurisdictions.[4] The states are not administrative divisions of the country; the Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government.

Download USA Native American Reservation Lands Shapefile Data

The Indian reservation system was created to keep Native Americans off of lands that European Americans wished to settle. The reservation system allowed indigenous people to govern themselves and to maintain some of their cultural and social traditions. The Dawes Act of 1887 destroyed the reservation system by subdividing tribal lands into individual plots.

Following classes of land reservation are established in USA

Indian Reservation Area
Alaska Native Village Statistical Areas
Hawaiian Home Lands
Oklahoma Tribal Statistical Areas
State Recognized Reservations
State Designated Tribal Statistical Areas
Tribal Designated Statistical Areas

There are 326 Indian Reservations in the United States.[1] Most of the tribal land base in the United States was set aside by the federal government as Native American Reservations. In California, about half of its reservations are called rancherías. In New Mexico, most reservations are called Pueblos. In some western states, notably Nevada, there are Native American areas called Indian colonies.

Alaska Natives previously had many small reserves scattered around Alaska; however, all but one (the Annette Island Reserve of Tsimshian) were repealed with the passage of the Alaska Native Claims Settlement Act in 1971.

There are Hawaiian home land, area held in trust for Native Hawaiians by the state of Hawaii under the Hawaiian Homes Commission Act of 1921.

Oklahoma Tribal Statistical Area is a statistical entity identified and delineated by federally recognized American Indian tribes in Oklahoma as part of the U.S. Census Bureau’s 2010 Census and ongoing American Community Survey.

A state designated American Indian reservation is the land area designated by a state for state-recognized American Indian tribes who lack federal recognition.

A tribal designated statistical area is a statistical entity identified and delineated for the Census Bureau by a federally recognized American Indian tribe that does not currently have a federally established Indian reservation.

How to do layer labeling in QGIS 3.2.1 – use and change label

Map is not just a picture in GIS, they represent several hidden information of objects. So in the upcoming days we try to understand it more and unearth the hidden data. After creating Basic Map, today we try our hands on layer labeling in QGIS 3.2.1 – use and change label. For extracting more information about the object we do labeling. It makes the layer interactive.

Need Data for study then Download Shapefile of Australia and United States Shapefile

layer labeling in QGIS 3.2.1

Labels are for providing more information about the object. This layer property depends on the attributes of the layer. So, lets start

How to get label dialog box

You can reach Layer Labeling dialog box by 2 ways:

By right click the layer >> Properties>> label (icon shown below)Or, Go to layer menu, select labeling.

Above map is not looking so attractive and informative.

In Labeling Dialog Box, it will show no label.
Click over it and select Single labels
Now come to the Label with (here you need to choose the field from attributes which is to be labeled). In the previous blog you learnt that. View attribute table
Lets select Name_0 from the drop down list.
Customize Font and Size.
Click Apply (live updates are available)

Now the map of continent is label like this.

So, this makes your map more informative. But still above map is not looking so good because off overlapping labels. These label are not placed in centre of object also. Multiple labels are also can be done in QGIS.

Convert CSV to KML

Hello guys, If you are looking for converting your CSV file into KML, you have landed on the right place. Here in this article we are discussing on how to convert CSV to KML in the easiest way possible.

A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values. Each line of the file is a data record. KML or Keyhole Markup Language is a collection of geospatial data on map and commonly used in Google Earth or google services

Using Online MapOG Converter Tool you can easily convert – CSV to KML. You can also do other GIS Data Conversion using this tool.

IGISMAP to Convert CSV to KML

For CSV to KML conversion go to MapOG Converter Tool, after logging in with your registered email and password. If you are a new user, click the Sign Up button in the Login popup and register to IGISMAP by filling the details.

There are three main steps for using GIS Converter:

Click on Tool Converter
Upload the data
Choose the format to which it should be converted

Step one is to upload your CSV file which you want to convert. You can upload the file from your system or select from the Recent Files.

Note:

Input CSV file should have location information in WKT format under a field named as WKT.
Input CSV file should not have any columns with empty column name between other fields.
Well Known Text (WKT) is an Open Geospatial Consortium (OGC) standard that is used to represent spatial data in a textual format.
WKT format represents a geometry with the name of the vector entity ie., POINT, POLYGON or LINESTRING followed by the longitude and latitude of the point feature or the vertex of the polygon in brackets. Example for each entity is given below
- POINT (169.03934 -46.32844)
- POLYGON ((76.61103048 9.85276413,76.612068 9.85303305,76.6124496 9.85362534,76.61269368 9.85513401,76.61374668 9.85455036,76.61466216 9.85409739,76.61630232 9.85377888))
- LINESTRING (-123.031531560501 40.4178012488507,-122.889863902657 39.8410114990573,-122.464860929125 38.7886231836447,-121.311281429538 37.473137789379)
Name of the field ‘WKT’ is not necessary to be case sensitive.

Here we have uploaded the CSV file containing the locations of counties of Washington. It contains locations recorded in WKT format as follows:

Step two is to select choose the output format of the converted file, in this case its KML. You can also set the Coordinate Reference System of your preference. As a default CRS will set to WGS 84 (World) [EPSG:4326]. Click on the Convert File.

Your CSV file will then get converted to KML file after a few seconds and will be available for downloading.

You can also choose to style the layer or continue with further conversion process by clicking the Convert Another File button.

Converted Files section from the dashboard contains the list of the details of all the conversion done in your account, providing both input and output data available for download their corresponding formats.

You can also search locations, add new datasets, edit layers and style the map according to your choice and requirements. As IGIS Map Converter Tool provides many benefits other then just conversion of data. This tool provides us to generate this published map in PDF or as image format.

Creating a Basic Map – QGIS

QGIS 3.2.1 works well for creating interactive maps, using good set of tools and symbology its become easy to implement. In the previous post we learn how to open and view vector data. So, today we are Creating a Basic Map – QGIS. For creating basic map we work with the vector data. Vector data is very common data format it describes the information in points, lines and polygons.

Creating a Basic Map: Adding vector layer

If you are not familiar with QGIS user interface then check our previous article QGIS 3.2.1 GUI

Open QGIS, we have a new blank map.
Add vector layer by choosing the icon.

In the dialog box, click on the Browse button. And navigate to the exercise data. (before using make sure to download the Exercise data)
Select the appropriate file, let say select road.shp
Here you are, this is your basic map
Save the project.

View attributes

If you are absolute beginners then question comes in your mind what is attributes. No worries when we are here, attributes is a data which store information about spatial data. It gives where, what and why about spatial data in tabular form.

So for roads, the layer we loaded in our basic map we will view its attributes. ->> Click on this icon for opening attribute table or you can use F6 or Go to Layer>> Open attribute table.

->> This attribute table provides more data about road layer, the lines that you see in the map are spatial data. These lines represents the roads.

Current basic map is not so easy to read. We will make it more understandable and interactive using Symbology (use of symbol).

Symbology

In the cartography design, symbology is technique to use symbols to represent graphic features of map. Visual appearance is very much important. Follow the steps for making your map more attractive –

Click two times on layer>> Layer properties dialog box will appear. Select symbology OR right on the layer>> click the layer properties in the menu. Symbology window shown below.

This all the creating a basic map – QGIS. Symbology is useful but the information contained in the layer is still hidden. In the next blog we will learn how to represent this data on map.

Hope it will be useful for GIS professional. Suggestions and feedback are most welcomed.

Basics of Cartography: Map, Map Projection

Cartography is a science which deals with the study and drawing of maps. Simply, we can say it is related to mapmaking methods. Cartography is made of two words ‘Carto’ means map or chart and graphy means ‘to draw’ or ‘to write’. Here in this article we will understand Basics of Cartography: Map, Map Projection.

Create beautiful Maps without writing a Code

Cartography in GIS

Cartography is related to representation while GIS is concerned with the analysis of spatial data. Sometimes, maps becomes more popular than their makers.

What is Map?

A visual depiction of all or part of an area on a flat plane is termed as MAP. Simply, we can say art of representing the surface of sphere or three dimensional into two dimensional body.

Types of Map Projection:

A map projection is the method to represent the spherical surface or object like that in two dimensional plane or flat surface. So therefore, there are both distortion and projection.

There are three major types of Projections:

The name of the projection is the shape that the image is projected onto.

Cylindrical Projection
Conical Projection
Planar Projection

Cylindrical Projection –

It is also known as Mercator Projection. One can imagine that a paper to be wrapped as a cylindrical around the globe, tangent to it along the equator.
In this projection size and shape of land near poles are highly distorted.
Area near the equator is lightly distorted.
Direction provided in this cylindrical map projection is accurate.
Cylindrical Map Projection is important for navigation.

Conical Projection –

In a conic projection area of the Earth is projected on to the cone. Simply we can say when we place a cone on the Earth and unwrap it, then the result of the projection is termed as conic projection. It is tangent to the Earth along a line of latitude.

Planar Projection –

Planar projection also known as azimuthal projection. In this projection a flat sheet of paper is tangent to Earth at one point. Point of contact may be any point on Earth surface; most importantly north and south poles are used for GIS database. Selection of point of contact depends on the reasons why we need projection or what type of function we want to do with the projection.

Even more Check : Formula to find bearing or heading angle between two points

See the Video for more clarification –

Hence, in this article we have covered Map projection. Hope this article filled the void by providing basics of Cartography.

Fleet Management System – Requirement | Features | Cost

This blog post describes a detailed overview of fleet management system – Requirement, Time, Technology and functionality. All features of Fleet Management Systems are going to be provided in this post in details.

Fleet Management System:

Fleet Management System is the range of functions which allows transportation companies in business to minimize the risk related with the improving efficiency, proven return on investment, productivity in business and reducing the overall cost.
It is a modular based system that has been developed for the group of transportation or large companies using fleets/vehicles with the sole intention of operating the business in a timely manner and reliable way.
Fleet management includes a range of functions like tracking valuable assets; automate the fleet reports, Management of vehicles and security & control of the fleet.
We provide simple and versatile fleet management system which is backed up by mobile access and live support. We emancipate your fleet with the sharpest technology, outstanding features and 24 hr access.
Now you can have more time to achieve your destination then less time to worry about the fleet operations and route.

Requirement Gathering:

What do client requires?

We have an absolute idea of our client’s needs for the Fleet Management System in their business, so here is a list of some main requirements we think that every client would want in their Fleet management system.
- Reduce fleet management time and cost
- Integrate fleet planning and execution
- Real time tracking of fleet which includes vehicle tracking, driver detail and asset details.
- Fleet scheduling management for on-time deliveries and customer service.
- Automation of fleet reports.
- Management of fleet/vehicle Maintenance
- Fleet utilization management
- All time fleet monitoring
- Route tracking
- Expense tracking
- Fleet analytics

Hardware requirements:

Implementation of fleet management system would require hardware entities for Real time tracking of fleets and driver, which can be listed as:
- Mobile Phones (iOS/Android/Windows): Any Mobile phone with the driver with GPS enabled in it can be used for the real time tracking of the vehicle and the driver. This provides you the location access to any of the mobile or immobile fleet.
- GPS Device: Live GPS tracking devices are ideal for most vehicle tracking needs. With live GPS tracking systems in the fleet, you can have access to real-time data about vehicle location, use, driving speed and etc. This can be used to track driving habits, route vehicles more effectively, keep tabs on equipment that is at high risk of theft, and improve your dispatch processes.
  You can use both of these for the combine and separate tracking of the fleet and the driver.

Software requirements:

These are some software requirements for the implementation of the fleet management system:
- Server: We can use any server for this management system but we prefer these two servers to be precise that we will be working on:
  1. NGINX Server – Nginx is an open source web server which can handle a website with a huge amount of traffic. It is a high performance web server developed with an intention to handle websites with large number of users. Its speciality is that it can run on a minimal amount of resources and handle a large number of requests.
  2. Digital Ocean Server – Digital ocean server or ‘droplets’ is a cloud server which is designed to store and server massive amount of data while making it easy and cost effective. Digital ocean server use KVM as hyperviser and can be created in various sizes. It helps in build deploy and scale cloud application faster and more efficient
  We personally recommend to use Digital Ocean Server, as it is much faster, easy and cost efficient.
- Socket connection: One of the main software components of the Fleet management system is socket communication server. It is a central server component that communicates with the tracking units. Socket connection is capable of communicating with multiple clients units using multiple threads as it establishes TCP/IP socket connection with the remote hardware units. When the fleet GPS is connected, the server will authenticate the connection and proceed to receive information from the device.
- RabbitMQ: RabbitMQ is the most used open source message broker software. It originally implemented the Advance message Queuing Protocol, which we will be using in this system. If we add single entries from server multiple times in database it will lock itself. So for preventing that from happening we will use RabbitMQ, which stores a information until a receiving server connects and takes a message off the queue. The receiving server then processes the information in an appropriate manner. So we can insert bulk information in the database in particular time as we want.
- Database: We will be using any of these two databases for storing the data we collected from the tracking devices of the fleet:
  1. PostGIS/PostGreSQL
  2. MySQL
- Mapping Systems: This is the main software component of the Fleet management system. This whole system is dependent on the web mapping of the data or information that the GPS devices provide. For mapping the data we can use any of these two Mapping systems.
  1. Google Maps: Google Maps is the tool which is used to display geographical information on a map which is in a widely accepted standard format for digital maps.
  2. OSM (Open Street Map): OSM is the software that creates and distributes the open source graphic data of the world. OSM has no restriction of technical or legal type. It allows free access to its map images and underlying map data. Here we can show our tracking data in real time.
Features:
- Managing vehicles:
  
  We will provide you all the information regarding the fleet/vehicles in the web portal’s dashboard like vehicles insurances details, vehicle renewable reminders and Maintenance/service reminders for vehicles etc. Our system provides automated reports for every penny you spent on the vehicle and each expense you are going to do in meantime. We provide vehicle orders bar where you can manage orders and get previous order details.
- GPS Tracking:
  
  The tracking unit collects the location information with the help of the GPS (Global Positioning System) device which we used in our system as hardware. Global Positioning System can be used for providing the route to the fleet. GPS formats collected information into the system–specific packet format and sends it to server via socket connection server. Global Positioning System tracking system uses the Global Navigation Satellite System (GNSS) network. This network incorporates a range of satellites that use microwave signals that are transmitted to GPS devices to give information on location, vehicle speed, time and direction by which we can manage Real time tracking of fleet which includes vehicle tracking, driver detail and asset details and Fleet scheduling management for on-time deliveries and customer services.
- Speed tracking:
  
  Driving with excessive speed is one of the main factors in fatal road accidents. Driving at a safe speed can help save lives. Fleet managers have an interest in keeping their drivers on the road and out of the troubles, and they also want to ensure that their fleet is operating in an efficient and timely manner. Speed tracking and reporting is a principal feature in Fleet Management System. In terms of reporting, our systems will report all offences to base in real time (even have the capacity to set an SMS alert).
- Geofence:
  
  Geofence is described as the circular areas which are defined around a particular location. It is set by the client in Fleet Management system by able to define the radius of the area. The GPS location of the center of the circle and the radius define a Geo-fence. If a vehicles GPS location is within the Geofence, then they are in safe area and if any vehicle go outside the area of geofence the client is notified by a text or email alert and the event is recorded.
- Automate the fleet report:
  
  We surely provide the automated report on each transaction or order. We provide automated report of the previous orders of fleet which you can check any time or download the file.
Cost:

Contact us at our mail or put a comment below to discuss the expected cost.

PostGIS, Geoserver and Leaflet | GIS Web Development

In this article we will see how data can query in Postgres and store and view at Geoserver and Leaflet i.e GIS Web Development with PostGIS, Geoserver and Leaflet. For this you will require setup of all three. You can visit our tutorial to install Geoserver For Linux or geoserver install in windows, Postgres and Postgis installation for Ubuntu 16.04. and a basic of Leaflet Js Javascript Library. If you are done with intial setup, then we can first start with to adding Shapefile in postgres by creating database in database.

PostGIS, Geoserver and Leaflet | GIS Web Development – Steps

Step 1: After installing Geoserver and Postgress postgis in your system you need to download dataset. The data we are using is shapefile for this tutorial, which you can download from the sources given in this post. The shapefile can be administrative boundary or road network etc. For any region. This website will help you to download zip file as well, which will have all supporting file for shapefile.

Step 2: Now you need to open Postgres, add database, table and add shape file using shp2pgsql. This all has been explained in our tutorial.

Step 3: Start Geoserver by running shell file provided in bin folder of geoserver. That can be run by executing the given command on terminal.

cd <path to Geoserver/bin>
sh startup.sh

Then Open browser and type

http://localhost:8080/geoserver

and login by using your credentials. Generally its admin as username and password as geoserver.

Step 4: Now create a new workspace on Geoserver. Now Move to workspace option in data section by providing required information. Create new store as PostGIS and provide information required. Here you need to give workspace name and data source name you created. If you want you can write the description about your data.

PostGIS, Geoserver and Leaflet | GIS Web Development

Now you need to provide connection parameter.

Dbype is the type of database, you can leave it as default or can specify your database type. Host and port: these are the parameter, which help geoserver to connect with postgres. The Host is space where database exist. The port to connect with postgres host, you can provide if you have set any otherwise make it as 5432.

Database: this is the database, which you have created using postgis. You are not sure about the name you can check it on pgAdmin or in terminal.

\l : this will provide you the list of available database. For this you must work with proper user-name.

Schema: to know your table, which you have created in database you can execute \d as this will provide you list of table associated database with their schema.

User and Password: this the USER with whom you have created database. In postgres you can create a new user with proper password.

Namespace: Namespace to be associated with the database. This field is altered by changing the workspace name. Remaining option you can leave as it is. And save the information.

Stpe 5: Now open the Layer option in data section, searched for your workspace and publish the layer.

Stpe 6: Here you will see tabs as data and publishing. In data tab you need to provide the reference coordinate system (CRS) by clicking on compute from data or compute from native bounds. After this you can save this layer with default styling. If you want to style your layer, which includes color, symbols etc. You can visit our tutorial styling vector data.

Step 7: Now moving to layer preview option in same data section. Here you can see your shape file.

Step 8: The shape file now can be render on map using leaflet javascript library.

For that you need to create HTML file, add leaflet library. After this create a div, which will contain map. Using L.map() and initialize the map and set view using setView() this takes center latitude longitude and zoom as arguments. You can check how to load a layer of polygon, point or polyline in leafletjs.

After that the shape file using L.TileLayer.WMS() , provide the base WMS URL, and specify whatever WMS options you need. The option can be layer, transparent and format etc. After this use addTo() function to add layer to initialized map. Open that HTML file on browser to see the map with rendered shapefile.

Hope this PostGIS, Geoserver and Leaflet | GIS Web Development helped you in creating a map layer of shapefile which is loaded in postgis, and added the wms layer from geoserver which is then served as map in browser with leafletjs. If you find any problem in understanding the same, do let us know by commenting below.

The Ability to map out and visually represent a region is necessary for planning responses to health crises and identified outbreaks which is done by GIS in Healthcare Industry.

GIS in Healthcare Industry :

In this post we are going to focus on How can we use GIS in Healthcare Industry and for that let us first talk about Healthcare Industry.

Health care industry is one of the most important and organized sector in the world, It deals with public medical care on a vast level. Health care industry is just beginning to realize the tremendous potential of GIS to benefit the public medical care. Either private or public organisation, both sectors are evolving innovative ways to harness the data integration and spatial visualization tech, which can be used with GIS in Health Industry.

Now That we had a brief of Healthcare Industry, lets discuss how would they make use of GIS in their working. GIS is helping every sector and so does it with the Health care. So lets see the benefits of the GIS in Healthcare Industry.

Benefits of GIS in Healthcare Industry :

Healthcare Industries are using the resource integration capabilities of geospatial technologies to create analytical and descriptive solutions for major health issues. Geographical Information System impersonates an important role in improving the quality of care, integrating and analyzing clinical data — alongside environmental data, increasing accessibility of services, finding cheap cost delivery modes, and preserving patient confidentiality while satisfying the needs of the research community for data accessibility.

Here we list out some of the main benefits of using GIS in Healthcare Industry:

Mapping :

GIS uses maps to analyze and understand the location of doctor or patients or hospitals. GIS mapping of data helps you make informed decisions with a web portal or application. It can provide a web- based portal for every patient or doctor, as you can find your closest doctor or right doctor for your specific need etc. This System includes comprehensive hospital listing locations and the no. of healthcare and social associated employees. These data provide a complete framework for exploring care provider locations.
Tracking :

Tracking is one of the most powerful aspect provided by GIS in Healthcare Industry. It has ability to use geography and other inputs to identify many new aspects. Let us discuss about two of them.
1. Tracking of Infectious Diseases : GIS can identify where diseases are most likely to spread next when an Infectious disease is effecting over a wide range of area. Collecting this kind of data can be essential to on-ground working personnel working to save lives because it enables them to prepare in advance for a disease and can severely impact.
2. Tracking Children Immunizations : GIS tracking can also be used as tracking child immunizations. GIS provides a way to move data from the project level so that it can be used by the entire organization, as it is used to gain a better understanding of Immunizations rates to determine which locations could be rescued during an outbreak.
Helps in Research – GIS in Health Care:

For broad regional treatment plans the collection of vast amount of accurate personal data is expected to reveal a great deal, but it can also greatly impact personalized healthcare. It has the potential to uncover long-term geographic trends in the health of certain demographics of people living within certain regions of the world. If the people or individuals have same health condition on same regions, like in a particular area, 70% of the population is suffering from the same common disease. So we can discover about why they all have the same disease? and we could open new realms of healthcare research.
Discovering Health Trends – With GIS Tool :

The Geographical Information System provides healthcare industry personnel the ability to recognize health related trends. The GIS offers public healthcare target healing endeavor based upon the result of health related trends. GIS offers a method for health care professionals in which they can address where the diseases are more prevalent or likely to be widespread in mean time and proactively begins implementation of preventative strategies or begin staffing skilled medical specialists healthcare professionals.
Improving Healthcare Services by GIS tool :

The Geographical Information System helps in identifying the greater needs of specific healthcare services in a large area or country. GIS helps in providing quick access to medical records, which is crucial to effective treatment. The use of GIS improves national healthcare services as it enables leaders and developers to work more closely with hospitals. And healthcare to take larger steps in addressing national healthcare needs. The geography of health care systems, which deals with the planning, management and delivery of suitable health services after determining healthcare needs of target community and service catchment zones. Improving healthcare services is the most important benefit of using GIS in Healthcare Industry.

So, This is how Healthcare System is using GIS for performing their tasks more efficiently. Geographical Information System is a powerful tool that has been successfully implemented to assist address a number of noteworthy health issues ranging from mapping to improved services. Using GIS in Healthcare System is one of the best method to have some control over the management and services. As the healthcare professionals start to adopt and integrate GIS. The number of benefits is likely to rise including the relationship between hospitals and communities. Which is perhaps the most important connection to be made.
